How to read from and write to a Unix domain socket
 
|
Hi, some days ago I asked on stackoverflow a question about Unix domain socket for Pharo. Bert told me it is possible but I didn't find the source code or examples. Could you please give me a few more hints? You can answer by email or on http://stackoverflow.com/questions/10759301/how-to-read-from-and-write-to-a-unix-domain-socket-in-pharo Thank you very much Best -- Damien Cassou http://damiencassou.seasidehosting.st "Lambdas are relegated to relative obscurity until Java makes them popular by not having them."

There are new primitives, in addition to the old ones. So far I think only Etoys uses them. I see for example a method SocketAddressInformation class>>addressFamilyLocal in addition to #addressFamilyINET4 and addressFamilyINET6, which must be good for something. It can use more than IPv4 for sure: NetNameResolver addressesForName: 'localhost' ==> an OrderedCollection( ::1(localhost),0(0)-inet6-stream-tcp 127.0.0.1(localhost),0(0)-inet4-stream-tcp fe80::1%lo0(localhost),0(0)-inet6-stream-tcp) This was added a couple years ago by Ian Piumarta and Michael Rüger. Levente ported the in-image code to Squeak last year, but it was never actually adopted: http://forum.world.st/Re-The-Inbox-Network-ul-100-mcz-td3618715.html This should be a good starting point for you. You won't find an example for domain sockets because the main purpose of the new plugin was to support IPv6. But Ian made it generic enough so it should work with any socket family. - Bert - |

Hi Bert, We had hard time to understand everything with Noury while working on Ocean (Network). The new primitives seems to be there in the new VMs (Cog). With Jannik we loaded the Etoys image side code to access them. But, it seems that it does not completly work (on mac).
Probably because the C plugin code is not in sync perhaps it has been modified in VMMaker branch and it has not been merged in Cog branch. My question is: do you know if the socket plugin code (all plateforms: unix, ios, win) is the latest one in cog repository (same as in VMMaker)?
Thanks, Luc 2012/5/28 Bert Freudenberg <[hidden email]>

The socket plugin updates seem to be missing in the Cog branch (checking both VMMaker-oscog-EstebanLorenzano.158 and VMMaker.oscog-eem.160). It should be OK to pull in the updates directly from VMMaker trunk, i.e. from VMMaker-dtl.274, although it may be that platform support code will also be needed for the Cog branch (I did not check this).

It seemed to me that recent sources from Jenkins only have primitives for ip4 and ip6.
Cheers,

Current socket plugin is not building ipv6 primitives... I don't know why, maybe a sync issue. Esteban On May 29, 2012, at 3:59 AM, Sean P. DeNigris wrote: > > > David T.

for your info mike spent time to port the IPV6 code from etoy to pharo and we removed it after because it was not working. Stef On Jun 5, 2012, at 4:35 AM, David T.

Thanks Stef, The unit tests definitely did not pass. I've been working on further updates to get it to work properly and also to pass all tests. It was a bit tricky actually, but hopefully it will be ready to go within a few more days.
